| 1 | Graphene Oxide Assemblies for Sustainable Clean-Water Harvesting and Green-Electricity Generation显示文摘CONSPECTUS:The urgent problems of water scarcity and the energy crisis have given rise to the development of a range of sustainable technologies with the great advancement of nanotechnologies and advent of attractive nanomaterials.Graphene oxides(GO),a derivative of graphene with an atom-thin thickness and abundant oxygen-containing functional groups(such as−OH,−COOH),are water-soluble and can be assembled into a variety of structures(such as fiber,membrane,and foam)with great potential in environmental and energy-related fields.As a typical precursor of graphene,GO can be easily reduced to graphene by chemical or thermal treatments to demonstrate excellent photothermal properties as well as tunable thermal conduction,which is highly desirable for efficient solar-driven water evaporation.The intrinsic large specific area of GO nanosheets can provide enough sites for ions adsorption and its porous assemblies facilitate the transport of water.In addition,the abundant functional groups allow the spontaneous adsorption of water molecules from the ambient environment and give birth to movable ions(usually protons)under the solvation effect.Once a chemical gradient is formed on the component,a remarkable electricity is generated from the directional transport of protons.Thanks to the excellent chemical properties of GO nanosheets,a wide range of assemblies with 1D aligned fibers,2D layered membranes and 3D porous foam can be easily fabricated by wet-spinning,solution-filtration,and freezingdrying methods.The various GO assemblies are able to exhibit abundant functions with remarkable weaving capability for GO fibers,superior flexibility for GO membranes,and exceptional adsorption capacity for GO foams.In light of all the advantages,GO and its assemblies are remarkably promising in the fields of sustainable development to meet the pressing challenges of water and energy crisis.In this Account,we will discuss the progress of clean-water production and green-electricity generation technologies based on GO assemblies.The fundamental working mechanism,optimization strategies,and promising applications are explored with an emphasis on the materials development.We also discuss the functions of GO assemblies in the water and electricity generation process and present their limitations and possible solutions.Current challenges and promising directions for the development of clean-water production and green-electricity generation are also demonstrated for their realistic implementations.We anticipate that this Account would promote more efforts toward fundamental research on graphene functionalization and encourage a broad exploration on the application of graphene assemblies in clean-water production and electric power generation systems. | Yaxin Huang Chengzhi Wang Changxiang Shao Boyu Wang Nan Chen Haibo Jin Huhu Cheng Liangti Qu | 2021 | Accounts of Materials Research2021，2，2： | 2 |
| 2 | Hazard Assessment of Co-seismic Landslides Based on Information Value Method:A Case in 2018 MW6.6 Hokkaido Earthquake,Japan显示文摘An MW6.6 earthquake occurred in eastern Hokkaido,Japan on September 6th,2018.Based on the pre-earthquake image from Google Earth and the post-earthquake image from high resolution(3 m)planet satellite,we manually interpret 9293 coseismic landslides and select 7 influencing factors of seismic landslide,such as elevation,slope,slope direction,road distance,flow distance,peak ground acceleration(PGA)and lithology.Then,9293 landslide points are randomly divided into training samples and validation samples with a proportion of 7:3.In detail,the training sample has 6505 landslide points and the validation sample has 2788 landslide points.The hazard risk assessment of seismic landslide is conducted by using the information value method and the study area is further divided into five risk grades,including very low risk area,low risk area,moderate risk area high risk area and very high risk area.The results show that there are 7576 landslides in high risk area and very high risk area,accounting for81.52%of the total landslide number,and the landslide area is 22.93 km^2,accounting for 74.35%of the total area.The hazard zoning is in high accordance with the actual situation.The evaluation results are tested by using the curve of cumulative percentage of hazardous area and cumulative percentage of landslides number.The results show that the success rate of the information value method is 78.50%and the prediction rate is 78.43%.The evaluation results are satisfactory,indicating that the hazard risk assessment results based on information value method may provide scientific reference for landslide hazard risk assessment as well as the disaster prevention and mitigation in the study area. | WEN Boyu XU Chong HE Xiangli MA Siyuan SHAO Xiaoyi LI Kai ZHANG Zhongjian LI Zhengfang | 2020 | Earthquake Research in China2020，34，1： | 2 |
| 3 | A real-world study of immune checkpoint inhibitors in advanced triple-negative breast cancer显示文摘Background:Triple-negative breast cancer(TNBC)is the most aggressive type of breast cancer.Immune checkpoint inhibitors(ICIs)have been widely used to treat various tumors and have changed the landscape of tumor management,but the data from real-world studies of ICIs for TNBC treatment remain limited.The aim of this study was to evaluate the efficacy of ICIs in the treatment of patients with advanced TNBC in a real-world setting and to explore possible correlates.Methods:The clinical data of advanced TNBC patients who received ICI treatment in the Chinese People's Liberation Army(PLA)General Hospital were collected.Treatment responses,outcomes and adverse events(AEs)were assessed.Results:Eighty-one patients were included in the study.The confirmed objective response rate(ORR)was 32.1%,and the disease control rate(DCR)was 64.2%.The median progression-free survival(PFS)was 4.2 months,and the median overall survival(OS)was 11.0 months.PFS and OS were longer in patients who achieved clinical benefit from ICIs and shorter in patients who received later-line ICIs and higher levels of inflammation;specifically,patients with higher TILs had longer PFS.Overall AEs were tolerable.Conclusions:ICIs are effective in the treatment of advanced TNBC,and the adverse reactions are tolerable.A panel of biomarkers including LDH,ALP,and bNLR were identified to predict the efficacies of ICIs in TNBC treatment. | Zheng Zhang Yadi Zhang Chuanling Liu Jiakang Shao Yimeng Chen Yimin Zhu Li Zhang Boyu Qin Ziqing Kong Xixi Wang Yutong Wang Deqin Huang Liqun Liu Yuxin Zhou Ran Tao Zengjie Yang Mei Liu Weihong Zhao | 2023 | Cancer Innovation2023，2，3： | 0 |
| 4 | Novel reusable sulfate-type zirconium alginate ion-exchanger for fluoride removal显示文摘It is still a challenge to eliminate efficiently fluoride ion from groundwater,especially to design and synthesis an adsorbent possessing high adsorption capacity,recyclability and wide pH application conditions.Herein we present millimeter-sized sulfate-type zirconium alginate hydrogel beads with 3D network structure(AHB@Zr-SO^(2−)_(4))that exhibited a maximum adsorption capacity of 101.3 mg/g with wide pH applicability(pH 3−9).This material have~2.5 times higher adsorption capacity than that of pure zirconium alginate hydrogel beads(AHB@Zr)and it was ascribed to ion exchange between SO^(2−)_(4)and F−on the surface of AHB@Zr-SO^(2−)_(4),which was verified via ion chromatography measurement coupled with X-ray photoelectron spectroscopy(XPS)and Fourier Transform Infrared Spectrometer(FTIR Spectrometer)analysis.Density functional theory(DFT)calculations indicated that the ion exchange process between SO^(2−)_(4)and F−in AHB@Zr-SO^(2−)_(4)was energetically favorable than OH^(−)and F^(−)in AHB@Zr.In addition,310 bed volumes(BV)of effluent was realized via column adsorption of groundwater containing fluoride on AHB@Zr-SO^(2−)_(4)and indicated that it is a promising candidate for mitigating the problem of fluoride-containing groundwater. | Tao Yua Yiliang Chen Yizhong Zhang Xin Tan Tao Xie Boyu Shao Xiang Huang | 2021 | Chinese Chemical Letters2021，32，11： | 0 |
